was sent to the bullpen and Worley was sent to Rochester. He emerged as an early ace, posting an ERA of only 0.93 after his first three starts, including a scoreless eight-inning performance against the Toronto Blue Jays in weather. He did not allow a home run in a game until May 10, when he gave up a three-run home run to Miguel Cabrera of the Detroit Tigers; Gibson lasted only two innings in that game, giving up six runs in the process. Gibson recorded his first MLB hit as a batter on June 2, a fifth-inning single against Matt Garza in a 6–2 loss to the Milwaukee Brewers. Gibson remained in the rotation for the season, finishing with a 13–12 record and a 4.47 ERA in 31 starts. He additionally struck out 107 batters in innings.

Both pitchers were placed on the 15-day disabled list on April 26, Santana with a lower back strain and Gibson with a right shoulder strain. He was meant to return on June 2, but began to experience back pain during his rehab assignment and had to be scratched from his scheduled start. Gibson was reinstated to the active roster on June 10, and he picked up his first win of the season on June 28, pitching seven innings of the Twins' 4–0 shutout against the Chicago White Sox. After struggling with stamina in a stretch of seven starts, Gibson pitched his first complete game victory on August 17, giving up only three runs on eight hits in a 10–3 victory over the Atlanta Braves. Because the Twins were playing a National League team at their home, Gibson also needed to bat in the game, and he became the first Minnesota pitcher to make five plate appearances in a game since Johan Santana in 2007. He went 6–11 for the year, with a 5.07 ERA and 104 strikeouts in 25 starts and innings. After a difficult start to the 2017 season, going 0–4 with an 8.20 ERA in his first six starts, Gibson was optioned to Rochester on May 4. Gibson understood why he was sent down, telling reporters, "I don't know that I've had a more frustrating stretch that I
